Hi, I'm wanting to replace the factory fitted CD/radio in my 2012 facelift Roomster with a fully fledged combined sat-nav/radio/cd/dvd/phone bluetooth unit . What are my options? I've been warned by my dealer's service manager that 'tinkering' i.e. adding new non-Skoda authorised and fitted kit could invalidate my warranty. Advice appreciated.

Might be worth looking at Kenwood's VAG designed ones - are you double din?

I have one, not cheap (inherited) but it has Garmin satnav and works very well. Only downside is that the IPod plugs in from the front only which I find annoying compared to my old car.
